LO OM.

SPECIFICATIONforming part of Letters Patent No. 595,417, dated December14, 1897.

I I Application filed July 16, 1897. Serial No. 644,752. (No model.)

To all whom it may concern-.

Be it known that I, PETER O. STADLER, a

, citizen of the United States, residing at Paterson, in the county ofPassaic and State of New Jersey, have invented a new and usefulImprovement in Looms, of which the following is a specification.

My invention relates to looms in which the shuttles are operated bymeans of a shuttle rack-bar, and the object of my improvement is -to'prevent the derangement of the shuttles by out of place. These impropermovements of the shuttle rack-bar cause the relative posi- I tions ofthe marionette-hooks to become so changed that they will be operated outof their proper order, resulting in a misweave and necessitating thestopping of the loom. The object of my improvement is to avoid thisdifficulty by steadying and controlling the action of the shuttlerack-bar and preventing its moving in its groove except as it is pulledby its actuating-cords, thereby permitting'a high rate of speed withoutdisturbing the normal action of the loom. This end I accomplish by meansof the devices shown in the accompanying drawings, which illustrate myimprovement as applied to a loom adapted to weave narrow goods, asribbons, in which the shuttle rack-bar is operated by means ofmarionette-hooks and the connecting parts usual in that form of loom. r

In the accompanying drawings, Figure 1 is a front elevation of a part ofa loom with my improvement attached thereto,showin g a portion of thebatten, partly in section, and the marionette-hooks and theiroperating-pin and the connections with the shuttle rack-bar. Fig. 2 is aplan view of the same, the marionette-harness being omitted for the sakeof clearness. In this figure the top of the batten is removed, exposingto View the shuttle rack- In looms not provided. with such a 0011- bar.Fig. 3 is a section, on an enlarged scale,

on the line 3 3 of Fig. 2. Fig. 4 is an enlarged plan view of thesliding plate, upon which is mounted one of the antifrictionguide-rollers, as hereinafter described.

Similar letters of reference refer to simila parts.

A is the batten, provided with a groove or channel, in which the shuttlerack-bar R is caused to reciprocate by means of the cords G O, which areattached at one end to the piece B,secured to the side of the shuttlerackbar R, and at the other end to the marionettesticks H H, whichlatter are operated by the pin W on the driving-rod L, engaging with thehooks h h in the customary manner.

D is the raceway of the shuttle, which latter is operated by means ofthe pinion E, in engagement with the rack-bar R in the usual way.

P is the pulley under which pass the cords C O. I do not claim anythingnew in the construction or arrangement of the foregoing parts, as theyare in common use.

F is an antifriction guide-roller mounted upon the batten A on one sideof the rackbar R and in contact therewith. Fis a similar roller mountedupon the sliding plate G on the opposite side of said rack-bar R. In thedrawings I have shown the centers of the rollers F F as being in thesame vertical plane with the axis of the pulley P; but they need not beso necessarily. The sliding plate G is provided with slots a a and isheld in position by the guide-screw headst IE, but so as to permit theplate being moved toward or away from the rack-bar R, the extent of suchmovement being regulated by the length of the slots (1 a. The plate G isalso providedwith the pin K, against which presses the free end of thespring S, thereby forcing the plate G inward and bringing the roller Einto contact with the side of the rackbar R. The other end of saidspring S is made fast to the batten at O, and the degree of pressure ofthe spring S upon the pin'K is regulated by the screw N. Theantifriction guide-rollers F F revolve With each movement of therack-bar R. .It will thus be seen that the shuttle rack-bar R may beheld as tightly as desired between the two antifriction guide-rollers FF and its movement prevented, exeept as the rack-bar is pulled to andfro by the cords C O. The loom may be run at a high speed without dangerof the rackbar running ahead of the proper action of the loom orrebounding when it strikes the end of the groove, and the derangement ofthe working of the loom consequent thereon will thus be avoided.

It is evident that the form, arrangement, and location of the partsabove described may be changed and other well known devices may besubstituted for the several parts without altering the principle of myimprovement.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a loom, the combination of the batten, the shuttle rack-bar andmeans for operating the latter, with antifrietion guide devices placedupon opposite sides of and in contact with said rack-bar between whichantifrietion guide devices the rack-bar is adapted to reciprocate, andmeans for regulating the degree of pressure of said antifriction guidedevices upon said rack-bar, substantially as shown and described. I

2. I11 a loom, the combination of the batten, the shuttle rack-bar andmeans for operating thelatter,withastationaryantifriction guiderollerplaced upon the batten on one side of the rack-bar and in contacttherewith, and a similar movable roller on the opposite side of saidrack-bar and means for pressing said last-mentioned roller against therack-bar, substantially as shown and described.

In a loom, the combination of the batten, the shuttle rack-bar and meansfor operating the latter, with a stationary antifriction guiderollerplaced on the batten on one side of the rack-bar and in contacttherewith, a sliding plate secured to the batten on the opposite side ofsaid rack-bar, an antifriction guideroller mounted on said plate, andmeans for moving said sliding plate toward said rackbar, substantiallyas shown and described.

4. In a loom the combination of the batten A, the shuttle rack-bar R andmeans for 0peratin g the latter, the antifriction guide-rollers F, F,the sliding plate G on which is mounted the roller F, and means forregulating the degree of pressure between said rollers and the rack bar,substantially as shown and described.

5. The combination of the following elements in a loom, viz., the battenA, the shuttle rack-bar R and means for operating the latter, thestationary antifriction guide-roller F, the antifriction guide-roller Fmounted on the sliding plate G, the said sliding plate G, and the springS, which latter is adapted to move said sliding plate toward therack-bar, substantially as shown and described.
